chore: Cleanup examples-grails-hibernate-groovy-proxy

- `application.yml`: Format properly with 2 spaces and group config settings better. Remove unused config.
- `logback.xml`: Correct faulty pattern
- `Customer`: Add no-args constructor needed for proxying
- `ProxySpec`: Remove unused imports
- `Application`: Remove unused imports and old comment
- `build.gradle`: Use correct dependencies and narrow the scopes. Switch from `tomcat-jdbc` to `HikariCP` as this will be the new default. Apply Gradle plugins in subproject instead of having logic and conditions in the root build file apply them - much easier to see what's being applied. Change version variable name from `hibernateGroovyProxy` to `yakworksHibernateGroovyProxyVersion`.
